• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder estimation method frame problem\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder estimation method frame problem ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder estimation method frame problem") OR ("api python python python programming"))*.
